Step-by-step explanation:
Given
t = 2 to 7
Required
Find the average speed over these intervals
The function is not given; so, I'll represent the function as s(t)
When
When
This gives:
As given m is a midpoint of ab. So am is half of ab.
So we can write
As given am = 3x+3 , ab = 8x - 6.
So
So x = 6.
So length of am = 3x+3 = 3*6 + 3 = 21
3x-13=2
move -13 to the other side
sign changes from -13 to +13
3x-13+13=2+13
3x=2+13
3x=15
divide both sides by 3 to get x by itself
3x/3=15/3
cross out 3 and 3, divide by 3 and then becomes 1*1*x=x
x=15/3
x=5
answer:
x=5
